Alexleblanc,
No worries about the test numbers, I know what u mean about the 5.3 btw. I had one and being a 2000 model it was good, and I had the 6.0 with the 4 speed trans... The newer 6.0 with the 6 speed is a different animal. The power is always right there if needed. I realized that u have the same fifthwheel as we have, the 6.0 pulls it really easy. KZ makes a great camper....
